Lou, You can check coolant flow quite simply also to verify that you are getting good circulation. Start with a cold engine....open hood, remove radiator cap, start engine, observe water through cap opening while the engine becomes warm enough for the thermostat to open. You should see the coolant moving in the radiator. You can pick the engine rpm up a bit to be sure the coolant is moving. This is a simple way of checking both flow, and the thermostats performance. This will rule out a flow problem. Hope this helps, George. |
